Computational Materials & Interfaces group
Computational Materials & Interfaces group, led by Professor Taehun Lee, utilizes computational simulation approaches to analyze and predict the characteristics of materials and their interfaces. Our group particularly focuses on semiconductor materials, including defects, that are applied in various fields such as solar cells, photocatalysts, and semiconductor devices and their interfaces with electrolytes. We employ classical electronic structure calculation methods such as density-functional theory and the Hartree-Fock method to characterize material properties at the electronic level. Moreover, our group conducts molecular dynamics simulations using machine-learned interatomic potentials, extending the scope of our simulations to device scales. Recently, our focus has turned toward integrating methodologies like data mining and machine learning with traditional simulation methods and material-related databases to speed up the discovery of highly functional materials.
